Buffer
Buffer is a social media scheduling and publishing tool available on web, iOS, Android, and as a browser extension. It supports scheduling posts to Twitter/X, Instagram, LinkedIn, Facebook, Pinterest, and TikTok from a single unified queue. The publishing calendar provides a visual overview of scheduled content, and the analytics dashboard shows reach, clicks, and engagement per post. Buffer's free plan covers three social channels with up to 10 scheduled posts per channel. The simple, focused interface makes it more approachable than enterprise social media tools like Hootsuite. It is widely used by indie creators, small businesses, and social media managers who want a consistent posting schedule without logging into every platform manually.
